If you receive a City of Round Rock utility bill, November brings a change worth checking.

New water and wastewater rates apply to billing periods beginning after November 1, 2026, under a three-year schedule adopted by City Council.

What are the new residential water charges?

For a standard 5/8-inch residential meter, the monthly water base charge is $19.60.

Water use is billed in tiers: the first 10,000 gallons cost $2.57 per 1,000 gallons; usage from 10,001 through 18,000 gallons costs $3.96 per 1,000 gallons.

Higher tiers are $5.27, $7.90 and $9.34 per 1,000 gallons as consumption increases.

At 5,000 gallons, the illustrative water charge is $32.45, including the $19.60 base charge but excluding wastewater and other fees.

At 10,000 gallons, the illustrative water charge is $45.30 on the same limited basis.

What about wastewater?

For the same standard meter, the monthly wastewater base charge is $16.20, plus $3.28 per 1,000 gallons of billed wastewater use.

Round Rock uses a winter wastewater averaging method, so billed wastewater usage may differ from the water consumed in the current month.

Other charges also appear on bills.

The City's published schedule lists $25.51 for garbage and recycling and $6.75 for residential stormwater drainage per dwelling unit.

More increases are scheduled.

The standard residential water base charge is scheduled to reach $20.58 in November 2027 and $21.61 in November 2028.

The comparable wastewater base charge is scheduled to rise to $17.00 in 2027 and $17.85 in 2028.

Your actual bill depends on your meter size, water usage, wastewater average and other services.

Check your recent bill and compare your usage against the complete City rate schedule rather than relying on a generic household estimate.
